It`s not cheap , but you can have custom headers made for around 1$1700. Or there is a custom builder that sends you a mock up kit . With pics and the mockup sent back they can build headers out of stainless. Cost is comewhere around $1400.
Hey Taylor. I have a `78 280z also. I am putting an ls1 in it. I am running panasports 16x7`s. What rim width do you have on the back and do you have the stock suspension? I also have mine lowered. I don`t want to cut the fenders for flares unless I have to. Mark
One of my coworkers printed out a test done on longtube vs. short tube headers. Even though a ford motor was used, they claim that below 350 hp on a v-8, shorties were fine. But above 350 hp that the long tubes would definately help. All of us ls1 guys should be using long tubes. Specially if you have done any mods. But I know there is the cost factor. If you don`t have a header maker near by there is a company that will send you a mock up kit. You fit the headers up the way you want them , tighten up the bolts and ship them back. They use stainless steel. Just google custom stainless steel headers and it should pop up.
I googled custom stainless steel header kit and a place called stainless headers popped up. I called them up. They send you a mock up kit. You design it the way you want it made , tighten the bolts up amd mail it in. One pair $1300. Five sets $900 each. Check out their site . Give them a call. If enough people are interested, we might get a great deal. Chris pointed out to me their collectors are merge collectors. Very expensive. The cost is cheaper this way because we spend several hours mocking up the headers. Not them. And they garrantee the fit. So what do you guys think?
